To add, it's not Ronaldo's fault for Al Nassr's failure; the culprit is the management, who didn't hire a coach who had achieved great success in different leagues, including the Saudi Arabian league. You can't expect a team to win titles just because they have the best player in the world. PSG is showing this in practice; even without Messi, Neymar, or Mbappe, they're performing much better compared to when they had these three good players.
Exactly. We can't blame Ronaldo due to the failure of Al Nassr in the last few seasons. It is also the mistake of the
club management because they couldn't build the team with proper players. IMHO, Al Nassr only focuses to improve the attacking line, they forget to improve the quality players in the midfield and defense line. Yep, this also happened in PSG. Even if they had Mbappe-Messi-Neymar at that time, they still failed to shine in UCL because they have no proper players in the other lines. Also, the
coach factor also takes the role because he is the one who applies the tactics and formation. A coach will also ensure that all players can cooperate as a solid team.
So, Al Nassr's management needs to see PSG's case as a great concrete example that the most important thing in a team is the coach. If they hire an inexperienced coach or one who has only achieved success in one league, they won't be able to handle Al Nassr well and, as a consequence, they won't be able to achieve anything great.
I agree that Al Nassr management needs to take a lesson from PSG case in the past. However I think it is not only about the coach, but it is also about improving all the lines of the teams.
